8:1 Differential-to-LVDS Clock Multiplexer
ICS854S058I
DATASHEET
General Description
The ICS854S058I is an 8:1 Differential-to-LVDS Clock Multiplexer
which can operate up to 2.5GHz. The ICS854S058I has 8
selectable differential clock inputs. The PCLK, nPCLK input pairs
can accept LVPECL, LVDS, SSTL or CML levels. The fully
differential architecture and low propagation delay make it ideal for
use in clock distribution circuits. The select pins have internal
pulldown resistors. The SEL2 pin is the most significant bit and the
binary number applied to the select pins will select the same
numbered data input (i.e., 000 selects PCLK0, nPCLK0).
Features
• High speed 8:1 differential multiplexer
• One differential LVDS output pair
• Eight selectable differential PCLK, nPCLK input pairs
• PCLKx, nPCLKx pairs can accept the following differential
input levels: LVPECL, LVDS, SSTL, CML
• Maximum output frequency: 2.5GHz
• Translates any single ended input signal to LVDS levels with
resistor bias on nPCLKx input
• Additive phase jitter, RMS: 0.065ps (typical)
• Part-to-part skew: 300ps (maximum)
• Propagation delay: 600ps (maximum)
• Supply voltage range: 3.135V to 3.465V
• -40°C to 85°C ambient operating temperature
• Available in lead-free (RoHS 6) packaging
